New method estimates translatitudinal Atlantic freshwater transport
Freshwater transport is related to the stability of the Atlantic meridional overturning circulation. Credit: Zheng Huayi Researchers from the Institute of Atmospheric Physics, Chinese Academy of Sciences and Xiamen University have developed an indirect method to estimate Atlantic meridional freshwater transport (AMFT) at different latitudes. The study was published in Geophysical Research Letters. The oceans, which contain 97% of Earth’s…

Whales may live much longer than scientists thought, with potential lifespans twice as high as previous estimates
Survival curves show that female right whales can live to very old ages, but humans are causing North Atlantic right whales to die far below their potential. Plotted for comparison is the survival curve for women in the United States as estimated by the Social Security Administration. Credit: Greg Breed Our new research published in the journal Science Advances shows…

A short-lived soda tax strengthens alternative estimates of the tax’s impact on consumer behavior: a study
Credit: Pixabay/CC0 Public Domain One of the most common assumptions made by tax policy makers is that increasing taxes will increase government revenue. But a new study focused on Washington state’s soda tax strengthens another estimate of the tax’s impact on consumer behavior. Researchers found that when Washington state enacted a soda tax, not only did it provoke a backlash…

Humans are already causing long-term global warming of 1.5°C, according to new estimates
Credit: Pixabay/CC0 Public Domain New research published today in Nature Geoscience by Dr Andrew Jarvis of Lancaster University and Professor Piers Forster of the University of Leeds shows that humans have already contributed to global warming of 1.5°C, measured since the period just before the industrial revolution and the 2000s. This indicates that it may be causing the The beginning…

Study provides refined estimates of permafrost loss in Alpine Asia due to future warming
The permafrost on the Qinghai-Tibetan Plateau is thawing, leading to recession. Credit: Jie Jiang Permafrost on the Qinghai-Tibet Plateau has thawed.
